-{{{model|FMB640}}} is able to go to GPS sleep mode if such mode is enabled.<br/>Sleep mode timeout starts counting when device is in STOP mode. After timeout is reached and all conditions for GPS sleep mode are met, device goes to sleep mode. While in GPS sleep mode, {{{model|FMB640}}} turns GPS module off and is still making new periodic records. As a result power usage decreases, in turn saving vehicle battery.<br/>{{{model|FMB640}}} will enter GPS sleep mode if ALL of these conditions are met:
-* {{{model|FMB640}}} has to be configured to work in GPS Sleep mode and sleep timeout is reached;
-* Device must have time synchronized with GNSS satellites and have GPS fix;
-* No movement by configured movement source or movement sensor is detected;
-* Ignition (configured ignition source) is off;
-* Forced wakeup is not set;
-* There are no SMS messages being received.
-{{{model|FMB640}}} exits GPS sleep mode if ONE of following conditions is true:
+While in sleep mode, {{{model|FMB640}}} sets GPS receiver to sleep mode but GSM/GPRS module stays active, in Sleep mode power usage can be decreased to save vehicle’s battery, because GPS module is turned off.
-* Movement by movement source or movement sensor is detected;
-* Ignition (configured ignition source) is turned on.
+{{{model|FMB640}}} can enter sleep mode if ALL of these conditions are met:
+*{{{model|FMB640}}} has to be configured to work in Sleep mode;
+*Start-up timeout has elapsed (5 minutes after every restart of the device);
+*No movement by accelerometer is detected;
+*Ignition is off;
+*USB cable is not connected.
+{{{model|FMB640}}} exits sleep mode if ONE of the following conditions are true:
+*Movement by accelerometer is detected (depends on accelerometer start settings);
+*Ignition is turned on (driven logic high);
+*USB cable is connected;
+*HIGH or PANIC priority eventual record is detected;
+While being in sleep mode FMB640:
+*cannot save periodical or eventual records;
+*send data to server;
